It will be noticed by referring to the plate, that when newly 

 emerged from the pupas, these moths have the singular habit of 

 clinging to a branch and suspending themselves therefrom. 1 have 

 known the moth to remain for hours in the same position, leaving for 

 flio-ht when night came. 1 am pleased to be able to say that Mr. Grant, 

 although surrounded by bush and bush insects has succeeded in 

 stamping this pest out of his orchard. These moths, it may be men- 

 tioned, are rarely seen in daylight, and although supposed by many 

 to be of rare occurrence, the insect is far from uncommon. In New 

 South Wales, Leto staceyi has its home, and as this splendid moth is 

 sometimes from 9 to 10 inches across the wings, and the grubs of a 

 proportionate size, it will be readily understood what enormous 

 damage is done by these to some of our finest timber trees. As to 

 the apparent scarcity of this moth, I think it may safely be asserted 

 that ants, of all other insects, are responsible for the task of keeping 

 this and other pests within reasonable bounds. 



Prevention and Remedies. 



On page 114, Part I. of " Tlie Dedructioe Insects of Victoria,'^ the 

 following instructions for use against the Cherry-borer are given 

 by me, and will sufltice for this species also. 



" Remove, or if possible have removed, all old and badly infested 

 wattle and other trees growing in the vicinity of the orchard. Give 

 the tree when dormant a spraying or two with either kerosene 

 emulsion, tar water, Quibell's mixture, phenyle, or any other solution 

 which would tend to make the flavour of the surface of the bark un- 

 palatable for the female to rest upon for the purpose of depositing 

 her eggs. After pruning, paint the stumps with a solution of tar 

 and grease. Remove all loose bark, and daub with a common 

 whitewash or similar kind of brush any of the solutions into the 

 crevices or crotches of the tree ; and to prevent the larvae from 

 descending from one tree and ascending another, a good plan 

 would be to paint the lower portion of the stem with a mixture of 

 kerosene, lime, tar, and grease. 



When the presence of this borer is suspected, first clear away the 

 sawdust-like matter before mentioned, the removal of which will 

 indicate the direction taken by the grub, but as the holes are usually 

 made in a horizontal position, the ordinary method of spraying should 

 be somewhat departed from. If the spraying pump and nozzle be 

 used, project, with as much force as can be commanded, the liquid 

 into the hole, being guided by the direction taken by the grub. 



In gardens where there are but few trees, small pieces of stick 

 dipped into a mixture of tar and carbolic acid (three parts of the 

 former to one of the latter) could be driven into the holes, which 

 will in most cases, cause the grub to shrivel up at once and die. 

 In large places this method would be, perhaps, too tedious, still the 

 services of children might be utilized with advantage for this pur- 

 pose, as the little sticks could be prepared by night around the family
